Aphthous Ulcer


Ulcerative stomatitis or canker sore

  • These are small sores or painful swellings on the inside of the mouth and on the tongue that appear without apparent reason, and disappear by themselves usually within ten days, leaving no scar.  They maybe caused by stress, spicy foods, or acid-alkaline imbalance.

  • Small (usually a few millimeters and rarely up to a few centimeters), painful ulcerations -- they usually have a yellow-gray center surrounded by a red halo
  • Usually painful for 7-10 days
  • Usually resolve in 7-21 days

  • Unknown, but probably viral

  • Topical corticosteroids in an adhesive base e.g. Triamcinolone acetonide 0.1% with Orabase Palin
  • Tapered 7-day course of prednisone in severe cases
